JOSEPH' GRQVE, 0F SPARKHILL, BIRMINGHAM, ENGLAND,v ASS-IGNOR T0 FREDERICK MQUNTFORD, OF BIRMINGHAM, ENGLAND.

GARB'URETEIR.

To LZZ whom it may concern:

' 4Be it known that I, JOSEPH GROVE, a sub- .ject of the Kin of Great Britain, residing at 627 Stratfor road, Sparkhill, Birmingham, England, have invented certain new which provision is" made for preliminary heating of the fuel and is particularly useful for heavy oils.

1 5, `5 provide improved means i'or eiecting the The principalobject vof` the invention is to preliminary heating and vaporization of the oil when starting the engine as well as durheating devices.

ing normal running` and to control conveniently the iowjof fuel past or throughl the In the accompanying drawings Figure 1 j shows, partly in section, a general elevation of one form of carbureter -constructed according to the invention, and Fig. 2 shows,

,inl section, a modification. Fig. 3 is a perjspective view of the homogenizer.

Referring first to Fig. 1 a casing o: is formed at its upper end with a carbureting chamber b and at its lower end with a chamber c which lcontains the homogenizer d.

The carbureting chamber b is preferably provided with inclined sides converging toward the lower end and terminating in a comparatively small orifice e leading centrally into the top of the homogenizing chamber c. The air is admitted at the top of the carbureting chamberbpithrough a valve f'hereinafter more 'iu'llycj "ascribed and the oil-isfadmitted throng suitable nozzle g projecting into the carbiir ing'chamber b so that the oil escapesat-"or near 'the center thereof.

The oily ueljisj supplied from any convenient sourcezas, for-example, an ordinarv float-feed- :regulating device 71,. Connection of theA carbureterand float-feed tank may be effected by aside-iiange 1I on the part a and a y controlled valve f for admitting air.

covered by a plate fm. carrying the spring- Such Specification of Letters Patent'.

Application led April 30, 1914. Serial No. 835,568.

valve'is preferably centrally arranged on the underside of the plate m and adapted, when moved upward by the spring n, to close the apertures o in the plate m. The spring 'n iS arranged betweenthe top of the plate m and a collar or the like p at the upper end of the Valve spindle.

A cylindrical closed casing g is secured to the aforesaid cover plate m and s provided at its Aupper end with apertures r, the effective area of which is adapted to be adjusted by a rotatably plate s mounted on said casing and havirigcorresponding apertures as shown. The-rotatable plate s is held in its adjusted position by any convenient means,

and adjustmentmay be ei'ected by an arm t.

The homogenizing chamber c is cylindrical being open at the bottom for the insertion of the homogenizer 0l and has vthe comparatively small central opening e, above re.

connected to the-lower plate 'w by a central stem v and the peripheral edge of the said part d fits the casing. Such edge is provided with a number of small inclined grooves w through which a part of the mixture passes and is thereby thoroughly broken up and mixed. The upper part of the j homogenizer is conical in shape leaving a small flat top m which comes opposite the opening e and is situated-a; slight distance therefrom. i M

A large number of holes gare provided in the upper part of the homogenizer, such holes being preferably drilled at about right angles to the conical surface and'being formed smaller at their lower ends than at the top ends.`

The casing a forming the carbureting chamber and homogenizing chambers is adapted to be secured on to the top of another casing 3 provided with a three-way valve 4:. The mixture after passing through the homogenizer passes into the top of this casing and then, normally, passes by way of abranch 5 through a tube heated bythe exintense 4 and operating to control the passage ofthe explosive mlxture to either of the heaters, and means for retarding passage of the explosive mixture past the primary heater in the direction of the length of the latter.

2. In an internal combustion engine, a

.carbureter, a valve-casing communicating therewith, an open-ended housing having a port opening into the valve casing, an electrical heating coil disposed within the housing and out of contact with the walls thereof to permit passage around the coil of the explosive mixture, and means for retarding passage of the explosive mixture past the primary heater in the direction of the length of the latter.

' 3. In an 'internal combustion engine, a carbureter, a valve casing communicating therewith, an explosive-mixture receivlng chamber constituting an extension of the valve casing, a coil unit having one end coupled with the valve casing and its other end discharging into the receiving chamber and having a portion of its length disposed within the exhaust pipe to constitute a heater for the engine, an openended housing arranged within the receiving chamber and having a port opening into the valve casing, an electrical heater disposed within the housing and out of contact with the walls thereof to permit passage of the explosive mixture around the heater in the direction of its length, and a valvein the casing arranged to control passage of the explosive mixture at will either to the coil unit or to the housing.

4. In an internal combustion engine, a

carbureter, a valve-casing communicating therewith, an explosive-mixture receiving chamber constituting`an extension of the valve casing, a coil unit having one end cou pled with the valve casing and its other end discharging into the receiving chamber and having a portion of its length disposed within the exhaust pipe to constitute a heater of the engine, an open-ended housing arranged within the receiving chamber and having a port opening into the valve casing, an electrical heater disposed within the housing and out of contact with the' walls thereof to permit passage of the explosive-mixture around the heater the ydirection of its length and a valvev l"1n the casing arranged to control passage of the explosive-mixture at will either to the coil unit` or tothe housing and means independent of the c'arbure'ter for supplying air to the receiving chamber 'at the point of discharge of the heated mixture. In testimony whereof I aix my signature in presence of two witnesses.
